What the LUOM TJ-A041 does

The LUOM TJ-A041 is a bi-directional HDMI 2.1 switcher that handles 8K at 60 Hz and 4K at 120 Hz with 48 Gbps bandwidth. It operates as a 2-in-1-out switch or a 1-in-2-out splitter for consoles, streaming boxes or PCs. A manual button toggles the active path while dual LEDs show the current state. It is built for users who need flexible routing between two sources and one display or one source and two displays.

Check your cables and power

Each HDMI cable run must not exceed 3 metres to maintain signal integrity at the highest resolutions. The unit ships with a DC 5 V power line that connects via micro-USB; attach it if the source devices cannot supply enough current on their own. Only one output is active at a time, so plan for a single display or a single source in any given moment. Verify that your displays and sources both support HDMI 2.1 for full 8K or 4K 120 Hz operation.

Build integration

The compact 12 by 6 by 0.08 inch enclosure weighs 1.2 ounces and fits behind a monitor or inside a media cabinet without blocking adjacent ports. It frees up HDMI inputs on the display by consolidating two sources into one port, or it frees up a source device by letting it drive two screens alternately. The PI3HDX1221 chip handles switching duties while supporting Dolby Vision, HDR10, HDCP 2.2 and 2.3, and high-bitrate audio formats for home-theatre setups.

Questions about this item

What comes in the box and do I need to buy any cables separately?

The package includes the bi-directional HDMI 2.1 switch, a DC 5V power line and instructions. HDMI cables are not included, so you will need to supply your own 8K-rated cables for each connection.

Should I use this as a 2-in-1-out switch or a 1-in-2-out splitter for my setup?

It works both ways: connect two sources such as a PS5 and Xbox to one 8K display, or one source to toggle between two displays. Only one output is active at a time.

What does the 48Gbps bandwidth actually deliver on my 4K 120Hz TV?

The 48Gbps link supports 4K at 120Hz with HDR10, Dolby Vision, HDCP 2.2 and 2.3, plus DTS-HD Master Audio and DTS:X for full gaming and cinema performance.
